Final answer:
Option B: After the passage of a warm front, surface winds shift from east to southwest due to the clockwise rotation of air around a high-pressure system in the Northern Hemisphere.
Step-by-step explanation:
With the passage of a warm front, surface winds shift direction from the east to the South.
Warm fronts occur when warm air moves into an area previously occupied by cooler air. As the warm air advances, it displaces the cooler air, causing the wind direction to change. In the Northern Hemisphere, surface winds associated with warm fronts typically shift in a clockwise direction. So, if the surface winds were initially coming from the east, they would shift to the south.
With the passage of a warm front, surface winds shift direction from east to southwest. In meteorology, this wind shift is associated with the movement of a warm front, where warmer air mass replaces a cooler one. When a warm front passes, winds tend to shift direction due to the clockwise rotation of air around a high-pressure system (anticyclone) in the Northern Hemisphere. Initially, as the front approaches, winds might blow from the east, but after the front passes, the winds come from the regions that the warm air is originating from, which is typically the southwest in many temperate regions.
